Cost Calculation on Loop Invariant on Arithmetic operations on RTL

2015-02-17 Thread Ajit Kumar Agarwal
Hello All: I can see the Loop invariant pass in the GCC on RTL considering the register pressure and the cost manipulation With respect to SET destination node in RTL. The Loop invariant takes care of only address arithmetic candidates of Loop invariance. In the function get_inv_cost, I can se
